This study contains data on the political, economic,
religious, ecological, and demographic characteristics of
113 nations in the years 1950, 1955, 1960, 1963, and 1965.
Originally collected by the Dimensionality of Nations (DON)
Project at the University of Hawaii, these data provide
information on political regime characteristics, such as the
number of political parties, electoral system, political
leadership, the nature of the political system, horizontal
power distribution, communist party membership, the legitimacy
of present government, the legality of government change,
freedom of opposition, major government crises, bureaucracy,
and the occurrence of assassinations, riots, general strikes,
protests, domestic violence, demonstrations, threats and
accusations, and purges. Economic variables focus on gross
national product (GNP), aid received from the United States
and Russia, national income, government expenditures,
government balance of payment, investments, imports and
exports, energy production and consumption, agricultural
production, and the economically active population. Demographic
variables include age, education, literacy, religion, ethnicity,
marital status, immigrants, and migrants. Other variables provide
information on the nations' bloc memberships, United Nations'
assessment of the nations, air distance of the nations from the
United States, number of nongovernmental organizations, number
of the nations' diplomats expelled or recalled, age of the
nations, and the nations' geography.
